Command Line:
-p[gpu_id]”Name”
apply profile “Name” to GPU with id=[gpu_id]
-c[gpu_id]”Name”
same as above, but with confirmation message that application started and everything went ok.
-r[gpu_id]
reset GPU with id=[gpu_id]
cp[gpu_id]”Name”
compare current values of GPU with id=[gpu_id] with profile “Name”, and eventually set this profile if not equal
cm[gpu_id]”Name”
compare current values of GPU with id=[gpu_id] with profile “Name”, and eventually set this profile if not equal, with additional message if not equal found
co[gpu_id]”Name”
only compare current values of GPU with id=[gpu_id] with profile “Name”, with message if not equal found
-consoleonly
displays all messages (eg. errors) in cmd.exe console window, instead of gui messages. Only commands that are put after -consoleonly are affected, example:
“OverdriveNTool.exe” -consoleonly -r0 -p0″1″ -r1 -p1″1″ -r2 -p2″2″ – will affect all commands
“OverdriveNTool.exe” -r0 -p0″1″ -r1 -consoleonly -p1″1″ -r2 -p2″2″ – will affect -p1″1″ -r2 -p2″2″ commands only

[gpu_id] – it’s the first number taken from GPU description, for single video card it’s 0
“Name” – name of the profile that was saved ealier, must be quoted if has spaces inside

example:
OverdriveNTool.exe -p0myProfile -p1″Profile 2″
In this example application starts without gui, then sets “myProfile” to GPU with id=0 and “Profile 2” to GPU with id=1 and then exit.

commands can be used all together, for example:
OverdriveNTool.exe -p0myProfile -r0 co1″Profile 1″
On configs with more than 10 GPUs [gpu_id] must have 2 digits, for GPUs 0-9 leading 0 must be added, example: 00,01,02,03,04,05,06,07,08,09,10,11,12. Usage example: -p05″Name”
It’s possible to use * as [gpu_id], which means it affects all supported GPUs, example:
-r* -p*MyProfile -p2″Custom profile” cm*MyProfile

Advanced:
-ac[gpu_id] GPU_P[num]=[value];[value][;0] Mem_P[num]=[value];[value][;0] Fan_Min=[value] Fan_Max=[value] Fan_Target=[value] Fan_Acoustic=[value] Power_Temp=[value] Power_Target=[value]
-ac is similar to -p command, applies values but without using profiles. Format is identical to ini profile. All not specified values will remain untouched. Can be used with other commands (-consoleonly, * as [gpu_id], -r, -p… etc.)
[num] – Pstate number, using # as [num] will apply to highest available Pstate for scpecified GPU
[value] – value, for GPU and memory PState first value is clock (MHz), second is voltage (mV), third optional ;0 makes this Pstate disabled.
Putting * as Memory or GPU value will skip applying this value, for example:
-ac0 GPU_P7=*;800 Mem_P3=1000;* (only applies GPU_P7 voltage=800mV and Memory P3 clock=1000MHZ)
-ac0 GPU_P4=*;*;0 (only disables GPU_P4 without changing it’s values)

-getcurrent – prints current values for all supported GPUs in cmd console window.

Additional info:
-Workaround for bug in 17.7.2 drivers, when driver sometimes uses default voltages instead of user settings: use reset and re-apply profile.
-It’s possible to disable/enable each P state. To do this click on P0, P1.. etc. label. If P state is disabled it will not be used by GPU.
-I2C currently supports: IR3567B (RX470, RX480, some RX5xx), up9505 (MSI RX5xx)
-If you prefer to not touch fan settings it’s possible to deactivate Fan section for each GPU. To do this press Ctrl + double click somewhere on the Fan box. It’s saved per gpu_id, so GUI or commandline will not touch fan settings for such GPU.
-To open Settings or SoftPowerPlayTable editor left click on top-left program icon, or right click on the titlebar.
-To change “friendly name” first enable it in settings, than right click on the gpu list to open menu
